By the time most analysts upgrade a stock, it is too late. The stock will be at its premium and further rising of the stock value is not a foregone conclusion. Borders' closing of its stores is already reflected in the stock price today.

However with the announcement coming in a few days of another ereader, that might cause for a little more uptick.

Tough call. The new reader might improve B&N's prospects, but they still have a large physical infrastructure that can use some downsizing. It might be worth a short-term profit, but I still expect their stocks to do some more rising and falling in the near future.

I'm not sure. If the strongly rumored Amazon tablet is real, and it's delivered at a good price point with an OS that isn't locked down. it could put a real dent in Android tablet and Color Nook sales.
